在尝试了很多之后，我发现 IN() 对我有用。

DELIMITER $$

USE `employee`$$

DROP PROCEDURE IF EXISTS `selectemployeebyids`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `selectemployeebyids`(IN empid VARCHAR(100))
BEGIN
    SELECT empname,salary,department from emp where empid FIND_IN_SET(empid) ORDER BY empid;

DELIMITER ;
